The usual support for arod line or a pitman.

The reciprocating rod line is tightly clamped in the clamping means and as the rod linemoves to and fro it causes the support -end. a 1 1.

line. I I

My type of clamp has been previously set forth in my application filed August31, 1928, entitled -;Shackle line equalizer, Serial No. 303,307. My aim is to provide a support which will elimie nate the above recited difiiculties and which will be easily and cheaply constructed.

My invention consists of an open bottom bearqing, a top journal with an integral roof and clamping means and a middle angle portion. This angle portion has an open bearing at its top which is complementary to the top journal, and a top journal with an integral roof, which is comv 'plementary to the bottom bearing.

to oscillate about the open bearing at its lower is that the bearings areexposed to thegweather' and the water washes the oil out ,of -the bearings; In the ordinary type of bearings which run in a bath of oil, any rain which may collect in v strain on them and even if allowed to move only a few feet when they break the sudden stop snaps Another advantage of my deviceresides in, the, integralroofsorjwebs which, are provided. to shield the bearings from rain and the like.

Another; feature of; my inventionis my novel means wherebythe lower journal will Vbelifted from its seatwvhen excessivef oscillation of theupright occurs. This means consists of a semicircular 'web whichnotflonly serves as aroof, "but also abuts againstthe'bottomvbearingand H consequently lifts the; lower journal from itsseat.

It willbe noted that the lower journal is undercut in order to take care of any sidewise movement which may-occur when these two parts separate.

, Also, I provide ribs'funderneath the roof which" 7 also aid in separating the-two parts when break: ageoccurs, Byathis latter method more oscillation movement;.- may be obtained and hencea deeper vat of oil forthe journal to submerge in may be obtained-.. 1 Still further objects or advantages subsidiary 5 or incidentaltotheaforesaid objects, or resulting from the construction or' operation of the inven-' tion as it may be carried into effect, 'will become apparentpjas' the saidqnvention is hereinafter further disclosed. i 5 v Lattain these obj ectsby the mechanism illused'intheac om n in rawing, in wh I F g-l t. er p iv vi of m swin n p-v port with the several parts in detached position.
